Figs:CL3/4:NS:LHAS:Waves:BTW:NAR:BTW:MAL:PB&S:

A1  circle L 3/4, 
    swing N

A2  hands across star L, gents drop out halfway, ladies keep going, 
    R hand to N to make ocean wave

B1 bal wave, N alle R until gents can reach forward to make diagonal wave
   bal wave, gents alle L until they can give R hand to partner 
   to make wave on other diagonal

B2  P balance/swing
 
Teaching tip: to get back into the dance at the end, gents stand right in  the
middle, facing the line.  Their partner faces away from the line, and these two
take right hands.  When the second wave in b1 comes along, they'll be in the
right place to be back in the dance.
 
At the end, the lady who is out has to cross the set to find her partner on the
other side to make the second wave.  This is the place most likely to cause
confusion.  If the lady doesn't cross, and her partner comes to HER, they'll be
on the wrong side of the set.  

But i don't usually call this unless i have a reasonably experienced group, who
will eventually figure out they're supposed to be on the other side.you may
have to encourage them to LOOK LEFT for new neighbors, as they may not end up
exactly across from them.
